Answer:
The sum is , simplified is .
Step-by-step explanation:
Add the numerators together.
<u>(4+3)</u> = <u>7</u>
5 5
Since the denominators are the same, there is no change there.
To simplify, you take away 5 from the sumerator(which becomes a whole number) and you're left with 2/5.
Answer:
What is the value of x in the equation?
Step-by-step explanation:
The edge length of a cube was to double, then the scale factor would be 1:2 (1 representing the original cube, and 2 representing the doubled cube). The ratio between the volumes is the scale factor cubed. Therefore the ratio of the volumes would be 1 cubed:2 cubed which simplifies to 1:8.
Final Answer: the volume of the cube with doubled edge lengths would be 8 times as large as the volume of the original cube.
y
= -1/5x Hope this helps. I think this is the right answer.
